1. I want to limit the player to one bullet at a time. Meaning that bullet must complete its journey (either impact with target or leave the screen) before another bullet can be fired. I've tried changing the rate of fire but it seems to influence absolutely nothing in the behavior at all. As fast as I can push a key, that's how often I can fire the turret.
2. I have set the turret to be triggered by a keyboard key press down and I want an object on the screen to animate each time that happens. Nothing fancy, just change colors to indicate the turret was fired. I've given the sprite two frames to toggle between but instead of ping ponging when the key is pressed, it does it as soon as I hit play and never again.
